Wanyama posted a message to supporters, club staff, and former teammates, picking out Jose Fonte in particular.
He wrote: "You guys have always been there to lift us up when we were down, and to celebrate with us when we were playing well. I feel really proud that I got the opportunity to wear the Southampton shirt.
"Secondly, football is a team sport and it wouldn’t be right not to thank my amazing teammates. Jose, thanks for leading the team and always being there to pick us up when we needed encouragement. Thanks to the rest of the team for always giving 100% effort, I will miss all of you.
"I also want to thank every member of the Southampton staff: those who work behind the scenes and never get credit for their contribution to our success on the pitch. We are nothing without you. I will never forget my time in Southampton Football Club, I will keep club forever in my heart."

Wanyama has had three impressive seasons at the Saints but had only one year remaining on his contract.
He has experience playing under current Spurs head coach Mauricio Pochettino, doing so on the south coast, and is expected to make an instant impact in North London, with Mousa Dembele suspended for the first three games of the Premier League season.
He is Tottenham's first summer signing, but is not expected to be the last, with the club needing reinforcements up front to help Harry Kane out.
